Re: How Did Hadrosaurs Survive? (Was: Hadrosaur "mummy" questions)

I'm all for tyrannosaurs moving quickly. But with a suspended phase?

I sort of liked that idea myself, until HP Brett Booth (or was it his wife?)
brought up an interesting argument a couple of months ago. Unless chasing
prey into the mounths of the larger adults was instinctive, how would the
young'uns know how to do this if their parents weren't already fast enough
to teach them? Many hunting behaviours are learned, and in this case, the
adult tyrannosaurs would likely have to show their kids the proper
technique. Am I making any sense? Where's Brett when you need him? :P
